Comparison of outcomes between surgical treatment of colorectal cancer metastatic to the liver and the peritoneum: Review of the literature

BackgroundLiver and peritoneum are two of the most common sites of colorectal metastases.MethodsWe searched for articles comparing outcomes of surgical management for metastatic colorectal cancer to the liver and peritoneum.ConclusionCytoreductive surgery/heated intraperitoneal chemotherapy has a similar safety profile and survival outcomes as hepatectomy for colorectal metastases after stratifying by resection status and should be incorporated earlier in the management algorithm for colorectal cancer patients with peritoneal metastasesMethodsWe performed a wide search on PubMed, EMBASE, and Google Scholar for articles comparing outcomes of surgical management for metastatic colorectal cancer to the liver and peritoneum. We focused on studies comparing their perioperative clinical outcomes as well as their oncological outcomes. The following words were included in the search: comparison, outcomes, metastasectomy, colorectal cancer, liver, peritoneal surface disease, hepatectomy, and cytoreduction.ResultsOne hundred and twenty studies were evaluated. Six of these studies met the criteria for this review.
